Technical details
An integer overflow in GIMP's PAA file decompression code calculates undersized memory buffers when processing image dimensions, leading to out-of-bounds reads past the buffer boundary. The vulnerability requires user interaction to open or preview a specially crafted PAA file and affects the plug-in process with potential for minor heap disclosure. The flaw is triggered by local file processing with no privilege escalation required.
